> Code for reading and writing binary DTDs using ASN.1 encoding
> -------------------------------------------------------------
>
> Key: HARMONY-1395
> URL: http://issues.apache.org/jira/browse/HARMONY-1395
> Project: Harmony
> Issue Type: Improvement
> Components: Contributions
> Reporter: Miguel Montes
> Attachments: ASN1_01.patch, ASN1_ITC-Contribution_20060905.zip
>
> The class javax.swing.text.html.parser.DTD has a method read() for
loading a binary DTD. The format of this binary file is not specified, so
the current implementation uses serialization. This approach has several
problems, so it was suggested in harmony-dev the use of ASN.1 to encode
the DTD information.
> Attached is a zip file with a set of classes for encoding and
decoding a
DTD, using the ASN.1 framework already in use in javax.crypto; and two
bdtds, one for HTML 3.2 and one for HTML 4.01. Also attached is a patch
for DTD.java and DTDUtilities.java.
